Functional and flexible, this guide takes an objects-first approach to Java programming and problem using games and puzzles. Updated to cover Java version 1.5 features, such as generic types, enumerated types, and the Scanner class. Offers independent introductions to both a command-line interface and a graphical user interface (GUI). Features coverage of Unified Modeling Language (UML), the industry-standard, object-oriented design tool. Illustrates key aspects of Java with a collection of game and puzzle examples. Instructor and Student resources available online. For introductory computer programming students or professionals interested in learning Java.

In Java Number Cruncher, author Ronald Mak explains how to spot-and how to avoid-the subtle programming miscues that can cause vexing calculation errors in your applications. An authority on mapping pure math to computer math, he explains how to use the often-overlooked computational features of Java, and does so in a clear, non-theoretical style.

Without getting lost in mathematical detail, you'll learn practical numerical algorithms for safely summing numbers, finding roots of equations, interpolation and approximation, numerical integration, solving differential equations, matrix operations, and solving sets of simultaneous equations. You'll also enjoy intriguing topics such as searching for patterns in prime numbers, generating random numbers, computing thousands of digits of pi, and creating intricately beautiful fractal images.

Java Number Cruncher includes:

*Practical information all Java programmers should know
*Popular computational algorithms in Java-without excessive mathematical theory
*Interactive graphical programs that bring the algorithms to life on the computer screen
*Rounding errors, the pitfalls of integer arithmetic, Java's implementation of the IEEE 754 floating-point standard, and more
*This book is useful to all Java programmers, especially for those who want to learn about numerical computation, and for developers of scientific, financial, and data analysis applications.

The Spring Framework is a major open source application development framework that makes Java/J2EE(TM) development easier and more productive. This book shows you not only what Spring can do but why, explaining its functionality and motivation to help you use all parts of the framework to develop successful applications. You will be guided through all the Spring features and see how they form a coherent whole. In turn, this will help you understand the rationale for Spring's approach, when to use Spring, and how to follow best practices. All this is illustrated with a complete sample application. When you finish the book, you will be well equipped to use Spring effectively in everything from simple Web applications to complex enterprise applications. What you will learn from this book * The core Inversion of Control container and the concept of Dependency Injection * Spring's Aspect Oriented Programming (AOP) framework and why AOP is important in J2EE development * How to use Spring's programmatic and declarative transaction management services effectively * Ways to access data using Spring's JDBC functionality, iBATIS SQL Maps, Hibernate, and other O/R mapping frameworks * Spring services for accessing and implementing EJBs * Spring's remoting framework Who this book is for This book is for Java/J2EE architects and developers who want to gain a deeper knowledge of the Spring Framework and use it effectively. Wrox Professional guides are planned and written by working programmers to meet the real-world needs of programmers, developers, and IT professionals. Focused and relevant, they address the issues technology professionals face every day. They provide examples, practical solutions, and expert education in new technologies, all designed to help programmers do a better job.

"Kuchana … does a good job contrasting patterns that may seem similar to the novice. … This is a useful addition to a collection on software design patterns. " - CHOICE, Feb. 2005, Vol. 42, No. 06 "Why am I so pleased with this book? What makes it any different than other design pattern books? Well, first of all the volume is huge. Kuchana's book covers all the original Gang of Four patterns plus another 20 or so patterns, including a couple of multithreading related patterns. Second, the text itself is very readable and doesn't cling too much on fancy words. The explanations are concise and to the point…All in all a very good choice for filling the gaping design patterns encyclopedia slot in your bookshelf. Highly recommended." "Partha Kuchana is an experienced Enterprise Systems Architect. He understands that patterns are not about things that are just good ideas, but that patterns are about capturing knowledge bred from experience. This hard-won knowledge is what Partha is sharing with readers of his book…Keep it handy for all those 'How do I do this in Java?' questions where you wish you had an expert in the office next door to provide answers. This book is the next best thing." Linda Rising, from The Foreword

Direct from the creators of the Java™ programming language, the completely revised fourth edition of The Java™ Programming Language is an indispensable resource for novice and advanced programmers alike. Developers around the world have used previous editions to quickly gain a deep understanding of the Java programming language, its design goals, and how to use it most effectively in real-world development. Now, Ken Arnold, James Gosling, and David Holmes have updated this classic to reflect the major enhancements in Java™ 2 Standard Edition 5.0 (J2SE™ 5.0).The authors systematically cover most classes in Java’s main packages, java.lang.*, java.util, and java.io, presenting in-depth explanations of why these classes work as they do, with informative examples. Several new chapters and major sections have been added, and every chapter has been updated to reflect today’s best practices for building robust, efficient, and maintainable Java software.Key changes in this edition include

• New chapters on generics, enums, and annotations, the most powerful new language features introduced in J2SE 5.0
• Changes to classes and methods throughout to reflect the addition of generics
• Major new sections on assertions and regular expressions
• Coverage of all the new language features, from autoboxing and variable argument methods to the enhanced for-loop and covariant return types
• Coverage of key new classes, such as Formatter and Scanner
